SASH-CORD FASTENER.

SPECIFICATION forming part of Letters Patent No. 787,592, dated April 18, 1905.

Application filed February 20, 1904. Serial No. 194,518.

To (all whom it may concern.-

Be it known that we, PETER S. STAUFFEE, a resident of Springfield,in the county of Hampden and Commonwealth of Massachusetts,and FRANK R. IvEs, a resident of Wallingford, in the county of New Haven and State of Connecticut, citizens of the United States of America, haveinvented a newand useful Sash-Cord Fastener, of which the following is a specification.

Our invention relates to improvements in what are technically known as sash-cord,

irons, which are in reality fasteners for attaching the ends of weighted cords to window-sashes; and it consists of a certain peculiar device hereinafter described.

The objects of our invention are, first, to afford convenient and efiicient means for attaching the end of a cord to a sash; second, to produce a fastener that can be easily and quickly secured to a cord of any reasonable size by one or more blows from a hammer and does not require a special tool for this purpose or call for the exercise of any particular skill, and, third. to furnish an inexpensive, strong, and sim ple fastener which will securely hold the cord in place in the sash. IVe attain these objects by the means illustrated in the accompanying drawings, in which Figure 1 is a perspective view of our fastener, showing it open ready to be applied to the cord; Fig. 2, a similar view showing the end of a cord in place and a hammer poised ready to strike a blow to close the iron on the cord; Fig. 3, a perspective view of the fastener and cord after the former has been.

closed upon the latter, and Fig. 4 a perspective view of a section of one side of a sash with the fastener and cord in position.

Similar letters refer to similar parts throughout the several views.

This fastener consists of a strip of metal bent vertically, so as to form two horizontal arms, which are equipped with a plurality of prongs turned inwardly from the edges thereof, while points rise vertically from the terminals of said arms. The points are adapted to engage the sash and the prongs to engage the cord, certain of said prongs penetrating deeply into said. cord from both sides,

the cord and others guiding and holding the same without penetration. The fastener may be punched out of sheet metal and bent into shape in a press.

Referring to the drawings, it will be observed that a strip of metal is bent at a so as to form two arms 6 of substantially equal length, said arms being horizontal in practice and the bend vertical. Three points 0 rise from the upper edges of the device at the terminals of the armsthat is, one is located at each free end and a third at the junction or bend a. Two points mightbe employed at or adjacent to the bend a in place of the single point 0. Then again one of the points 0 at the open terminal'of the fastener might be omitted and the other used alone with the point or points at or near said bend; but the present construction is believed to be the best in all respects. From one or both of the long edges of both arms 12 (preferably from both of such. edgesthat is, the upper and lower edges) intermediate of the points 0 prongs d and d project inwardly, the latter being smaller or shorter than the former. These prongs are designed to penetrate the cord e when the iron is closed. Guide-prongs (2 project inwardly from one or both of the long edges of the arm I), which is provided with the shorter prongs 61', said prongs 6 being located one on each side of each of said prongs d. The prongs d form a trough, as it were, in which the end of the cord 6 may be laid preparatory to closing the fastener thereon, the shortness of the prongs cZ permitting said cord to be thus placed.

To attach the fastener to the cord e, place the former upon some firm support in the position shown in the first two views, lay the end of said cord onto the prongs d between the guide-prongs d, and then strike the upper arm a sufiicient number of times with the I hammer to bend the arms 6 closer together I and drive the prongs (Z and (Z into the cord. This operation can be performed quickly and easily, with the result that the arms I) are forced toward each other and tight against the cord, while the'prongs (Z and d are driven The prongs cl, which have served their purpose as guides, now bind upon the cord and assist materiallyin fastening the device thereto and preventing any liability of the cord to work loose from the iron. Without these guideprongs it would be somewhat difficult to center the cord, while forcing the arms toward each other with a hammer, so as to drive the penetrating-prongs into the cord along lines corresponding with a diameter of the same. The tough and tenacious nature of the metal of which the device is constructed prevents the arms from separating after being closed upon the cord, and no ordinary usage will separate the cord and fastener. The parts now appear as best shown in Fig. 3.

In Fig. 4 a fragment of a window-sash f is shown, in the side of which is cut a recess J. The recess 9 opens through the edge of the sash f next to the base of the groove or runway in the casing in which the window operates and is designed to receive the fastener. A groove h for the cord 6 extends upward from the recess 9 to the top of the sash. The fastener attached to the cord as above described is inserted sidewise into the recess 9, with the cord in the groove 7L. 1 The pull on the cord 6 draws the points 0 into firm engagement with contiguous portions of the edges of the recess r, and there is no liability of displacement of the fastener while the sash is being raised or lowered in the casing, which latter assists in holding the device in place. The

fastener may be readily removed from the sash if the same be taken from the casing.

It is plain that variations in construction course, that the points 0 at the open terminal of the device should be at the extreme ends of the arms 6.

What we claim as our invention, and desire to secure by Letters Patent, is

1. As a new article of manufacture, a sashcord fastener comprising a strip of metal bent vertically to form two horizontal arms and provided with points at the open and closed terminals and with spurs projecting inwardly from the arms intermediate of said terminals.

2. As a new article of manufacture, a sashcord fastener consisting of two arms joined together at one end, points rising from the upper edges of said arms at their junction and free ends, prongs adapted to penetrate a cord extending inwardly from the upper and lower edges of both of said arms, and guide-prongs extending inwardly from the upper and lower edges of one of said arms both sides of the firstmentioned prongs.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
